Question

what is thermic reaction and give the equation​

Answer 1

Answer:

$Thermit \;\; Reaction : It\;is\;the\;reaction\;in\;which\;aluminium\;is\;oxidised\;by\;another\;metal\;oxide\\Mainly \; Fe_{2}O_{3}$

$Reaction:Fe_{2}O_{3}(s)+Al_{solid}------>2Fe_{(liquid)}+Al_{2}+O_{3}_{(solid)} \\+large\;amount\;of\;heat$

It is mainly used to weld the broken tracks because molten iron is formed in this reaction which, when poured on the cracks, cools down and sets in the cracks, welding them along the way:)
